Auto-expire only deletes things while recordings are in progress.  So, 
if your file system is already full, MythTV can't start a recording, so 
it won't expire anything.

Delete a show manually (i.e. change Watch Recordings to show Live TV 
recording group and then Deleted recording group) and when you delete a 
show from Deleted recording group, it will be removed from the disk.

Then, MythTV should be able to start recordings, so it should be able to 
run the expirer.  If that doesn't help, you'll need to post complete 
logs showing the auto-expire run so we can figure out why it's refusing 
to delete anything.

Also, note that if you've enabled slow deletes, MythTV will delete each 
individual show slowly, but at a rate faster than your recorders can 
record.  If other processes are writing to the disk, you could easily 
fill it up faster than MythTV is deleting shows.
